exception-handling

问题 I have multipler classes annotated with @ControllerAdvice , each with an @ExceptionHandler method in. One handles Exception with the intention that if no more specific handler is found, this should be used. Sadly Spring MVC appears to be always using the most generic case ( Exception ) rather than more specific ones ( IOException for example). Is this how one would expect Spring MVC to behave? I'm trying to emulate a pattern from Jersey, which assesses each ExceptionMapper (equivalent

问题 The program asks for the user input for the double num 1 and double num 2 and if there is an exception I want it to ask again for the input of num 1 and num 2 public static void main (String[] args) { Scanner sc = new Scanner(System.in); double num1, num2; int error = 0; int text; System.out.print("Enter 4 "); text = sc.nextInt(); do{ try{ if(text == 4){ System.out.print("Enter number 1: "); num1 = sc.nextDouble(); System.out.print("Enter number 2: "); num2 = sc.nextDouble(); double quotient

问题 I could see several topics on try - catch but doesnt seem to discuss errors if any from finally block itself. I found that the error is not handled if it is in finally block. What would be the ideal way to manage finally? For eg. below is a mail function. if there is any error in try block, finally will execute the quit method which itself is not initiated so an unhandled error occurs. So is it better to ensure there is no errors occur in finally block? def send_email(ldap, email_address,

问题 I am implementing an JEE7 web application. During my work i have found a problem with handling my custom exceptions. I edited my account's property to have a non-unique login field.

The problem is, the exception is not propagated out of the facade class and it is not
